Improvements introduced in the object of the Main Patent No. 313,595 on "production electrocontroller apparatus", which comprises a time totalizer device operated through a relay whose coil is connected to the secondary of an intensity transformer in which the primary is traversed by the electrical current of the working circuit of the machine, which are characterized in that the secondary of the welding transformer is connected to the coil of a relay whose contacts are closed when excited, the power circuit of the time totalizer, so that when the supply voltage of said relay is reduced to zero due to shorted electrode ground, the said relay is de-energized and the hour counter supply circuit is open even if the load relay is energized.
